What does this fault code mean?
The additive dosing module (ADM) monitors the level sensor in the additive tank. If the module receives a signal from the sensor that is faulty or implausible, the code is set. The sensor is built into the additive tank and cannot be replaced on its own.
Possible causes
- Poor contact, resistance or corrosion at the terminals
- Break in the signal wire, or a short to ground or to supply voltage
- Damaged additive level sensor
- Damaged additive dosing module (ADM)
What you can do
- 1Check the connector at the additive tank for looseness, contact resistance and oxidation
- 2Clear the code and see whether it returns; a single fault can be a temporary disturbance
- 3If the code returns with no visible cause, the additive tank may need replacing because the sensor is built into it
- 4Restart the module with diagnostic equipment after any repair
- 5After the repair, check that the code does not come back
Symptoms you may notice3
- Message in the text window of the display
- Yellow warning symbol and text message in the display
- Maintenance or service indication in the display
